Iron Man Model 50 (Earth-1112)
In Earth-1112, Tony wore this armor during his last year with the Avengers before the deaths of Captain America, Hulk, Vision and Scarlet Witch against Ultron.
The Model 50 is an advanced modular suit,integrating various weapons and gadgets as well as testing new technology. The suit's wing stabilizers enable Iron Man to fly at speeds of Mach 5 and they double as air brakes. The Arc Reactor runs on a cleaner power source that would carry over to the Model 51 armor,which can also draw power to the repulsors efficiently.
The suit brought back a classic Iron Man trait: It can collapse and store into a briefcase. The armor plating operates like the MK XLII from the MCU and they can also extend the black and gold nanomesh. The nanomesh is incredibly durable and is resistant to bullets and fire.
During the fated final battle against Ultron, the Model 50 was severely damaged and was left that way for nearly a year. After Iron Man joined the Defenders, he repaired the armor and stored it in the armory of the Retribution, the team's Helicarrier,for emergencies only. When SIGMA attacked the Defenders on the Retribution, the A.I. disabled the Model 51, prompting Tony to suit up in this suit to fight SIGMA.
The Model 50's system was run by JARVIS before the A.I. was destroyed by Ultron in a taunt. FRIDAY was originally planned to run the Model 50,but she was destroyed by SIGMA,which paved the way for Jocasta to run all of the Defenders tech and the Iron Legion, as well the Model 50 and Model 51.
